UNITED STATES PATENT OFFICE:

GASOLINE MIXER.

Application filed August 4, 1922. Serial No. 579,562.

To all whom it may concern Be it known that I, CHRISTIAN HAUss- MAN, a citizen of the United States, residing at Gary, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in Gasoline Mixers, of-which the following is a specification.

This invention relates to fuel mixers for internal combustion engines and particularly to gasoline engines, and it has for its object the production of means for more completely atomizing the fuel in its passage from the carburetor to the engine, and at the same time more intimately mixing the fuel with the air.

Of the aocompanyingdrawings, Fig. 1 isan elevation 'of a gasoline engine showing the manifold and carburetor thereof, the uptake of the manifold being broken away to disclose the mixing device which embodies the features of my invention; Fig. 2 is a perspective view of the device removed from the uptake; and Fig. 3 is a central sectional view thereof.

The engine 2 of the drawing has a manifold 3 and an uptake 4 to the manifold. The atomizing and mixing device which I have invented comprises a casin 5 which may be of any suitable shape an material. I prefer a cylindrical metal casing having an external diameter slightly less than the internal diameter of the uptake to the manifold. Within the casing is rotatably mounted a member 6 which is pivoted in the casing in any suitable manner, such as by means of a pin 7. The member may be of any suitable shape. I prefer for the purpose the ring or circular band shown. It is desirable to have the member balanced on the pivot so that it will rotate-freely without tending to stay in any particular position, but the shape will be suitable if, when suspended, it will be rapidly rotated by the ascending gasoline or other fuel. To decrease the friction of rotation I prefer to have bosses 1 formed in the inner wall of the casing so as to hold the member slightly away from the wall of the casing. The casing 5 is mounted in any suitable manner in the manifold, preferably in the uptake 4 as indicated. And I prefer to provide on one end of the casing the flange 8 which is positioned between the flanges 9 of the uptake and the carburetor and the device is thus held firmly in place.

In operation the gasoline as it passes through the uptake and the cylinder 5 starts the member 6 to spinning, as it is seldom that the currents on both sides of the pivot will have equal effectson the balanced member, and any slight inequality in these two currents is sufficient to start the spinnin This spinning of the member very greatl y disturbs the passage of the gasoline and not only mixes it much more thoroughly, but particles of gasoline which have condensed or which have not evaporated are atomized by the action of the rotating member, and thus the mixing is still more improved; so that the fuel reaches the cylinders of the engines thoroughly mixed and in the most suitable condition for complete combustion.

In order to assist in the atomizing and mixing I constrict somewhat the internal diameter of the upper end of the cylinder 5 by forming thereon a conical shaped end or depressions 10. The effect of this constriction is to form an obstruction to the flow of the gas and to compress slightly the gas as it streams through the constricted portion; so that as it passes out of the upper end of the casing 5 and expands, a decrease in the pressure is produced which sets up eddy currents, thus more thoroughly mixing and atomizing the-gas, and at the same time the gases are forced through the openings 11 in the constricted portion of the wall, and

this also assists in mixing and atomizing the ases. The constricted end with the openings 11 coact with the rotating member 6 by receiving the irregular currents of gases passing away from the member 6 and preventing uniform and regular flow thereof by still further disturbing the currents, so that the mixing and atomizing is thus made very complete. The openings form bypasses for transmitting some of the fuel beyond the constriction.

I claim as my invention:

1. In an internal combustion engine, a manifold, a sleeve mounted in said manifold, a pin mounted in said sleeve and extending transversely thereof, a ring rotatably mounted on said in with the pin positioned diametrically wit reference to the ring.

2. In an internal combustion engine, a

manifold, a sleeve mounted in said manifold,

5 a pin mounted in said sleeve and extending transversely thereof, a ring rotatably mounted on said pin with the pin positioned diametrically with reference to the ring, and

a constriction in said sleeve adjacent said ring. 1

In testimony whereof, I hereunto set my hand.

CHRISTIAN HAUSSMAN.
